Cedar Isle Auto BMW
Useless cretins.
A week after purchasing the M5, I sent it in to Cedar Isle for a DIS Diagnostics and a Compression Test, due to the car being seriously sluggish and down on power. I had also requested that they test a spare set of MAFs which were in the car, and informed me which were buggered and which worked ok.
I was told to arrive at 7AM and wait for an hours or so for the car to be complete. I arrived at 7AM and patiently waited in the coffee area.
By 8:30AM, nobody had even looked at my car yet. Eventually I had to get a lift to my office at 9:30AM.
I was promised that the car would be ready before lunch, and ended-up having to telephone several times throughout the day to get an update. Every time, I was told "It's not ready". Eventually I went through at 16:30 and had to wait ANOTHER HOUR for the car to be finished.
The results I got, were pretty useless. Apparently one of the seat-heating elements was 0.02 volts under spec and nothing else was wrong with the car. When I asked for MAF test results, I was apologised to and informed that the mechanic had gone home already. The compression test showed a whole cylinder bank being down on compression - but no sensors were faulty.
Eventually I got the car diagnosed by a mate of a mate and it revealed the following:
Bank2 Exhaust Camshaft Sensor = FUBAR
A quick trip to JSN Motors, saw me picking-up two Exhaust CPSes (one for each bank) and I then prepared myself for a simple job, which ended-up taking close to 2 hours because there's no space to get-at the sensor from the top of the engine.
With the new sensor in, the SECOND I cranked the starter-motor, I could already feel that the engine was healthier. Took it for a drive and it's an absolute MONSTER. Fishtailing and tail-out cornering like it should.
I then did a compression test myself, with an old unit that I inherited from my grandfather..
No problems at all.
So I wasted my time and my money, with a useless and pointless "checkup" from Cedar Isle Auto.
DO NOT take your car there.
